SPECIFICATION forming part of Letters Patent No. 519,162, dated May 1,1894. Application filed November 23,1893. Serial No. 491,776. (Nomodel.)

.To all whom it may concern:

Be t known that I, ANTONIGNATZ SCHMIEDL, a citlzen of the United States,and a resident of the city of Philadelphia, in the county ofPh1ladelphia and State of Pennsylvania, have lnvented certainnew anduseful Improvements in Shoe-Beading Devices, of which the following is aspecification.

My invention relates to devices for form- [0 ing an even edge forstitched shoe seams in which the stitched and turned edge is pushed orforced out from; the inside to present a regular line preparatory to theoperation of hammering the turned stitched edge to flatten and make itof smooth and regular finish. In shoe uppers the leather is sewed to thelining and the sewed pieces are then turned right side out to inolosethe rough edges of the stitched parts. The infolded or turned in seamof] the leather edge is then pushed out from between the sewed partsagainst the line of stitching for the purpose of. giving a uniform edgeto the seam, so that when the seam is flattened out the edge will besmooth and regular. This flattening is done by hammering as the work ismoved over an anvil. The seam is then finished bya line of stitchingclose to the turned edge. For effecting this seam finishing work I haveproduced an 3 improved beading device which I will now describe inconnection with the accompanying drawings and will point out in theclaims concluding this specification the parts and combinations of partswhich constitute my in- Vention. i Referring to the drawings: Figurelrepresents in perspective a machine embracing my improved beadingdevice. Fig. 2 is a verticalsection of the same. Fig.3 is a front 4 Viewof such device. Fig. 4 is a side view of the same. Figs. 5 and 5 showthe double faced cam for actuating the front seaming finger or blade.Fig. 6 shows a piece of the scalloped upper illustrating the beadingaction of the front finger or blade in pressing out the edge of thescallops. Fig. 7 shows in cross sectional View the action of the frontseaming finger or blade upon the turned leather at the stitched edge.Fig. 8 shows a similar view of the action of the back seammg fingerorblade in pushing out the top of the scallop. Fig. 9 shows the seam afterit has been beaded and flattened; and Fig. 10 shows the position of thefingers or blades when the rear finger is acting as in Fig. 8.

As I have devised the seaming fingers or blades they are arranged on theopposite sides of a fixed-finger a, and the movement of the. frontfinger b, is lateral and to the right side only of the fixed finger a,while the rear finger c has a vertical movement. While the front fingerI) is acting against the leather to ceive a short shaft 6 which hasfixed thereon a driving pulley f, on one side of which is a double facedcam g g, and on its other side is an eccentricQh, the function of whichll will presently state.

The fixed finger a is forked at its lower end to permit the placing andworking of the drive pulley, cam and eccentric. Upon the back of thefixed finger is connected the finger or blade 0 by means of screws '5,11, which pass through slots 0 c, in said finger to permit it to have avertical reciprocating movement imparted to it by the eccentric h whichthe back finger embraces by its yoke end 0 Upon the front side of thefixed finger is connected a similar finger or blade I), by means ofscrews j, j, to permit it to have alateral reciprocating movementimparted to it by the double faced cam, and a co-acting spring 7a. Forthis purpose this finger has a short cross slot j through which thelower screw passes to hold the finger properly in place. These mov--able fingers terminate in thin fiat rounded ends b c, at the rounded enda of the fixed finger with which they co-operate to push out andspreadthe stitched folded part of the leather in, a way which Ishall presentlystate. A spring Z0 is connected to constantly press lthelower end of thefront finger 12 against the face of the double cam. The cam isdivideddiametrically to form identical acting faces 9 g for the purpose ofgiving to the finger four vibrations to the one revolution of the cam;while the eccentric gives by one revolution, to its connected finger, anupward and downward movement.

The relation of the front finger b to the rounded end a of thefixedfinger and to the cam, is such as to cause the beading end of thefront finger to move only beyond the front sid'eof the fixed finger sothat its right edge will act against and push out one side of thescallop, While the left edge of the fixed finger a will act to hold thework against such pushing action as seen in Figs. 3 and 6, the workbeing moved by the operator over and upon the beading fingers to theleft as indicated by the arrow 2. This pushing movement of the finger isvery quick against the inner side of the fold at the line of stitchingand regular edge along the stitched parts.

arms of the operator holding the work, and it.

' is evident that the finger acting twice on the same side and part ofthe scallop, will give a better and smoother outward pressing actionthan would result from a single pressing action of the finger on thesame part of the seam or scallop. In this seaming operation, thestitched edge when the leather is turned right side out, is so adjustedupon the fingers as to bring the inner lapped and stitched edge outsideor in front of the front-finger so that the three fingers will bebetween the lapped leather parts and will act wholly upon the leatherand not upon the lining, as seen in Figs. 7 and 8. The cam stands withits greatest points of elevation in the line of the greatest elevationof the eccentric, so that while the front finger is acting against theright side of the scallop, the back finger will act against the top ofthe scallop above the top of the fixed finger as seen in Fig. 10. It isimportant to observe that the spring acts to give the front finger itspushing action as seen in Fig. 3, against the scallop and therebycushions such action and prevents its liability to burst the line ofstitching, so that the cam acts only to move the finger b to the leftand to compress the spring so that it will act to move the finger to theright while the cam is traversing its lowest part g against the springpressed end of said finger. The front finger having two pushingvibrations during one revolution of the operating cam gives theadvantage of a quick action without increasing the speed which in suchmachines is about sixteen hundred revolutions per minute,'and morecompletely pushes out the seam at the points of the joining of thescallops; while the back finger has a positive and limited movement upagainst the full curve of the scallop and against which pushi'ng actionthework is held by the hands of the operator. It is the double pressingaction of the front finger on the same part of the scallop during onerevolution of the cam that allows the latter to be run with less speed,and lessens the bad effect of the jarring upon the hands and arms of theoperator; and it is theindependentaction of the two fingers-onesidewise, and the other upwardthat gives to the seam and to the scallopits proper shape and regular finish; and it is the relation of themovement of the front finger to the fixed finger that causes the latterto support the left side of the scallop while the front finger ispushing and forcing out the right side of the scallop away from thefixed finger.

The eccentric strap 0 may be provided with an adjustable wear-pad Z, seeFig. 2, preferably of leather on which the eccentric acts and by whichlost motion from wear may be taken up by means of a screw on pressingthrough the strap and bearing upon the pad which may be secured to theinner side of the strap. The cam acting end of the front lever may havea leather wear plug n bearing on the cam to prevent wear, as in Fig. 3.The

scalloped edge having been properly expanded and given its properuniform shape, the work is then laced upon the anvil of ahammeringdevice to flatten and finish the beading as seen in Fig. 9, and for thispurpose I attach the beading device to a base which contains a hammerdevice, as seen in Fig. 1. I make this attachment by forming a socket rin the end of the base to receive the upper step part 8 of the beadercasting, and firmly support it upon the bench by the aid of screws topassing throughthe base and clamped upon the stepped casting, so thatthe two devices may be sold as one machine for beading and hammering,but both not necessarily operated at the same time. As this seamhammering device is made the subject of a separate and distinctapplication for apatent filed of even date herewith a descriptionthereof is deemed unnecessary herein and no claim is made to such devicein this application.

I claim as my improvement- 1. In a shoe beading device, the combinaionof a fixed finger blade, a finger blade mounted on the front and afinger blade mounted on the back of said fixed finger, the said backfinger having avertically reciprocating movement and the front fingerhaving a laterally reciprocating movement, and mechanism for operatingsaid movable fingers, substantially as described.
